Protecting Against Email Viruses

Computer viruses are files that can attack your system and damage your programs and documents. Most viruses are spread when someone sends you an email message with an unexpected file attachment—and then you open the file. It's just too easy to receive an email message with a file attached, click the file to open it, and then launch the virus file. Boom! Your computer is infected.
